Deputy Chief Timothy Hanlon told The Enterprise that police were conducting a welfare check after being notified by a social worker that James Patrick Lewis, 23, was a danger to himself or others.

When police arrived at approximately 7:30 p.m., Lewis became agitated, grabbed a kitchen knife and locked himself and his mother in a room at their Elm Place residence.

The supervising officer called in a tactical response team with a negotiator, but the request was canceled after Lewis allowed his mother to exit the room. He was taken into custody and charged with kidnapping, and assault and battery with a deadly weapon.

His mother suffered a minor injury to her hand from the knife, Hanlon said, but did not need medical transport.

Lewis, who Hanlon said in known to his department, was taken to Signature Healthcare Brockton Hospital on a Section 12 or involuntary mental health evaluation order.
